Meet the Doctors


Dr. Heather Eggenberger

Dr. Heather Eggenberger grew up in Marysville, WA and attended the University of Washington for her college education. She received her bachelor of science degree in Neurobiology and chose to follow in her father’s footsteps by becoming a dentist. Dr. Eggenberger was pleased to accept the offer to attend UW School of Dentistry after comparing it to many other programs.

This highly respected program is ranked in the top tier of such programs and has an emphasis in implant dentistry and complex reconstruction.  In addition, she was mentored by specialists in all fields of dentistry.

She especially focuses on remaining up-to-date with the latest product recommendations, materials, and techniques in dentistry. It is important to Dr. Eggenberger that she is providing the best care possible to her patients and that they have a comfortable experience.

Dr. Eggenberger and her husband, Jon, have a little boy and a baby girl which makes life so fun!  In their spare time, the Eggenbergers love to be outdoors. Their hobbies include camping, hiking, skiing, and playing volleyball. They especially enjoy spending time with their friends and family.
